Video processing and color adjustment
- Crop, switch and scale video sources for the LED display.
- Use multi-screen display and single-layer crossfades.
- Adjust hue, saturation, contrast and brightness compensation.
- Control brightness by network-port group and adjust color temperature with independent RGB controls.
- Support 3× and 4× virtual-pixel modes.
- Use a multifunction card for automatic brightness control.
Low-latency operation
Specification V2.0 lists a one-frame minimum under low latency and a zero-frame minimum under lag-free processing. It does not explain the operating conditions for these two statements in that feature list. Confirm the required processing mode, firmware and complete signal chain before relying on a particular latency figure.
